Summary
This document is a formal correction notice published in *Frontiers in Cognition* on March 4, 2026, addressing an error in the funding statement of a previously published article titled “Cognitive load-dependent effects of HD-tDCS on the executive vigilance decrement: insights from aperiodic EEG activity” by Hemmerich, Lupiáñez, Martín-Arévalo, and Cohen Kadosh. The original article, published in 2025 (DOI: 10.3389/fcogn.2025.1677285), investigated the impact of high-definition transcranial direct current stimulation (HD-tDCS) on executive vigilance, utilizing aperiodic EEG activity as a key metric. The correction does not alter the scientific methods, data, results, or conclusions of the original study; rather, it rectifies an administrative inaccuracy regarding the attribution of financial support. The specific error identified was in the display of the funding source for research project PID2024-157672NB-I00. In the original publication, the funding statement was incorrectly listed as “MCIN/AEI/10.13039/501100011033.” The correction clarifies that the accurate designation should be “MICIU/AEI/10.13039/501100011033/FEDER, UE.” Consequently, the correct and updated funding statement reads: “This work was supported by the research project PID2024-157672NB-I00 to EM-A, funded by MICIU/AEI/10.13039/501100011033/FEDER, UE.” This change ensures proper credit is given to the Ministry of Science, Innovation and Universities (MICIU) and the State Agency for Research (AEI), along with the European Regional Development Fund (FEDER), which supported the work of author Elisa Martín-Arévalo. The significance of this correction lies in maintaining the integrity of academic record-keeping and proper acknowledgment of funding bodies. While the scientific content regarding cognitive load, HD-tDCS, and EEG spectral parameterization remains unchanged, accurate funding attribution is essential for transparency in research reporting. The original article has been updated to reflect this correction. The document also includes standard publisher notes stating that the claims expressed are solely those of the authors and do not necessarily represent the views of their affiliated organizations or the publisher. No other aspects of the original research, including the experimental design involving executive vigilance tasks or the analysis of aperiodic exponents and offsets, are affected by this administrative update.
